General Description
The Twinflex Multipoint ASD is a plug-in type smoke detector that utilises a photo-electric sensing
chamber to make a measurement corresponding to smoke density. The device also incorporates
a thermistor sensing circuit to allow for accurate heat measurement. These elements allow the
device to be configured to a smoke, heat or combined setting. This device is only compatible with
the Twinflex control panels (and their associated detection and alarm equipment) and may also
incorporate a sounder beacon (ignore all references to sounders/beacons if your device has no
sounder/beacon).
Before Installation
The detector must be installed in compliance with the control panel installation manual. The
installation must also meet the requirements of any local authority.
Spacing
Fike recommends spacing detectors in accordance with
interference, detectors should not be fitted any closer than 500mm (preferably 1000mm) to a light fitting or any other source
of IR or EMI. In addition to this recommendation the device should be mounted so that the indication LED is facing towards
the light fitting. For more specific information regarding detector spacing, placement and special applications please refer to
local authority.
Note: As with other optical detectors, this device should not be located where subjected to high levels or pulses of
light or infra red light, as this may cause false alarms or faults.
Device Installation
All wiring must be installed in compliance with the recommendations laid out by any local authority as well as any special
recommendations documented in the control panel installation manual. The cabling used should be of a 2-core 1.5mm
screened, fire resistant type (e.g. FP200 equivalent), and is to be wired in the form of a screened 2-core radial circuit (with no
spurs) from the control panel, terminating at the last ("End of Line") device.
Fix the detector base in a suitable horizontal position using the two screw slots provided, remembering to allow enough cable
length for termination. You may then terminate your cables directly into the terminal block according to the terminal labels. It
is important to maintain the screen continuity in order to protect against data corruption from interference.
Please note that the Multipoint ASD is not compatible as an End of Line device for older V3 Twinflex Panels.
